Oppo HA-2 - Page 5

Introduction
Thank you for choosing the OPPO HA-2 portable headphone
amplifier and USB DAC. The HA-2 draws upon the success
of the HA-1 desktop headphone amplifier and is optimized for
portable use. Featuring a hybrid class AB amplifier and a
USB DAC supporting 384 kHz PCM and DSD256, the HA-2
offers high performance digital-to-analog conversion for both
Apple’s iPhone/iPod, Android devices, PC and Mac
computers. A 3.5 mm input works with the remaining portable
music players that do not have a USB-compatible digital
output. Convenience features such as VOOC rapid charging
and a mobile device power bank make the HA-2 a true
companion for music on the go.
